Antique Dealers: 1% of sales revenue, for everything sold which includes Ivory in its manufacture, given to a wildlife fund, and marked on an invoice as such, with a seal, and with a certificate presented (or some kind of paperwork) to that dealer everytime a sale is made, and to show the dealer as having participated in a 'give back' scheme.

Auctioneers: 1% of final hammer price including commissions, for anything which includes Ivory in its manufacture, given to a wildlife fund, and marked on an invoice as such, with a seal and a certificate presented to that auction house.

A voluntary agreement, not mandatory.
